I hope I am posting this correctly, as you asked, but here goes!
My family are the MACMILLANS, long time residents of Knapdale, Argyll, Scotland. As far back as I've gone, so far, are my great great great great grandparents, Angus MACMILLAN & Mary GALBRAITH. Their son, John, b. abt. 1823, married Elizabeth HAMILTON. John & Elizabeth's daughter, Margaret MACMILLAN, b. abt. 1862, married Dugald MCGREGOR, in 1883. This is my line & I have quite a bit of other info. to share, if anyone out there feels they might be connected. Thank you!
